PROSECRETIN Meaning and
Definition
-
Prosecretin is a peptide hormone that functions as a precursor molecule for the formation of the hormone secretin. It is primarily produced and secreted by cells in the duodenum, a section of the small intestine, in response to acidic conditions caused by the presence of chyme (partially digested food) entering from the stomach.
The secretion of prosecretin occurs in an inactive form, and it requires specific enzymatic reactions to be converted into active secretin hormone. Once activated, secretin hormone is responsible for regulating several physiological processes involved in the digestive system. Specifically, secretin stimulates the pancreas to release bicarbonate ions into the small intestine, which helps neutralize the acidic chyme and create an optimal environment for the digestion and absorption of nutrients.
Prosecretin is synthesized as a larger protein molecule that contains the amino acid sequence for secretin hormone within its structure. Upon secretion into the blood, prosecretin undergoes cleavage, a process mediated by specific proteases, resulting in the release and activation of the secretin hormone.
Overall, prosecretin plays a crucial role in the control and regulation of digestive processes by serving as a precursor molecule for the production of secretin hormone, which stimulates pancreatic secretions to maintain the pH balance in the small intestine.

Etymology of PROSECRETIN
The word "prosecretin" is a technical term used in the field of endocrinology and has a relatively straightforward etymology. It is derived from combining two components: "pro-" and "secretin".
1. "Pro-" is a prefix commonly used in biology and medicine, indicating that something is in an immature or inactive form, or it precedes a more active or mature state. It comes from the Latin word "pro", meaning "before" or "in front of".
2. "Secretin" is a hormone produced in the small intestine that plays a crucial role in the regulation of digestion. The term "secretin" was coined by British physiologist Sir Ernest Starling in 1902. It comes from the Latin word "secretum", which means "secret" or "to secrete".
